PROBLEM TO BE SOLVED: To provide a piston pump for a brake device having a novel configuration of less inconvenient elements, for example.SOLUTION: A piston pump for a brake device comprises, for example: a housing including a first concave part and a second concave part, having a partition wall part for dividing the first concave part and the second concave part and having a through-pass hole at the partition wall part for connecting the first concave part with the second concave part; a cam positioned at one side in a longitudinal direction from the partition wall part so as to push the first end part of a penetration member passing through the through-hole toward the other side in the longitudinal direction; and a piston stored reciprocatively in the longitudinal direction in a pump chamber provided at the other side of the longitudinal direction rather than the partition wall part so as to reduce the pump chamber as the penetration member pushed by the cam toward the other side in the longitudinal direction is moved.SELECTED DRAWING: Figure 2

    【課題】例えば、より不都合の少ない新規な構成のブレーキ装置用のピストンポンプを得る。【解決手段】ブレーキ装置用のピストンポンプは、例えば、第一の凹部および第二の凹部が設けられ、第一の凹部と第二の凹部とを区分する隔壁部を有し、隔壁部に第一の凹部と第二の凹部とを繋ぐ貫通孔が設けられた、ハウジングと、隔壁部よりも長手方向の一方側に位置され、貫通孔を貫通する貫通部材の第一の端部を長手方向の他方側に向けて押すカムと、隔壁部よりも長手方向の他方側に設けられるポンプ室内に長手方向に往復移動可能に収容され、カムによって長手方向の他方側に向けて押された貫通部材の移動に伴ってポンプ室を縮小する、ピストンと、を備える。【選択図】図2
